Hello,

Can you tell me how to find the sides of he triangles in Q1 and Q2 in the attached drawing

they are right angled triangles

in question 2 i found that a=1.9 and b=1.3 using Soh

but i want to know If i can use $\displaystyle a^2 = b^2 + c^2 - 2bc(CosA)$

I want to be able to use other forumlas than a^2 + b^2=c^2

Please help thanks
